Application filed July 20, 191 2. Serial No. 710,702.

To all whom it may concern Be it knownthat I, Vrcron LINDBERG, a citizenof" the United States, residing at Fairpo'rt Harbor, in the county ofLake" and State of Ohio, have invented new and useful Improvements inLife-Boats, of which the following is a specification.

This invention is an improved life boat for use on vessels and consistsin the construction, combination and arrangement of deviceshereinafterdescribed and claimed.

One object of my invention is to provide an improved life boat'of novelform which is practically unsinkable and which can not be swamped oroverturned by a heavy sea.

Another object of my invention is to provide improved means forreleasing the life boat from the supporting skids.

In the accompanying drawing :F igure 1 is partly a side elevation andpartly a transverse sectional view of a life boat constructed inaccordance with my invention, showing the same in place on supportingskids. Fig. 2 is a horizontal sectional view of the same.

The hull 1 of my improved life boat is circular, has a flat bottom 2which is also circular and is of less diameter than the hull and isarranged concentrically with reference thereto, there being an annularoverhang 3 above the bottom which connects the same to the sides of theboat. The top 4 of I the boat is substantially semi-spherical in formand is flattened on its upper side to provide a circular concentricallyarranged deck 5 which is preferably provided wtih a rail 6, as hereshown.

My improved life boat is preferably made of iron or steel but may bemade of any other suitable material. The top l of the boat is providedwith window ports 6"and with hinged lights 7 to close the said ports,screws 8 being provided to securely fasten the lights in a closedposition and the hinged lights being provided with suitable packing 9 toeffect water-tight joints around the sides of the window ports. Thesewindow ports provide means for entering and leaving the life boat whenthe lights are open, and to facilitate entry into the boat through thewindow ports, the top of the boat being provided on its outer side withrungs 11 which are arranged below the window ports and of which anysuitable number may be provided.

Owing to the shape of my improved life ing capacity is secured, so

boat, the same, when afloat and when the lights are closed, isabsolutely tight against the entrance of water and, hence, the boat cannot be overturned or sunk in a heavy sea nor can it be drawn under bythe suction of a sinking vessel. At the center of the top of the boat isaventilating funnel 12 which is provided with a cowl l3'to prevent theentrance of spray. Below the ventilating funnel is a tank 14:, which isheld in place by supports 15 and is open at itsupper side. In the eventthat spray should enter the ventilating funnel, it will be caught inthis tankand prevented from ,wetting the interior of the boat. On theoverhang 3 are seats 16 which are arranged radially and extend entirelyaround the boat and each of these is provided with a hinged back 17which may be lowered in order to convert the seat into a couch. Owing tothe circular shape of the boat and the arrangement of the seats on theoverhang, maximum seattively small life boat constructed in accordancewith my invention will suflice for a considerable number of persons. Thelife boat is preferably equipped with a provision chest 18 and with afresh water tank 19, for the subsistence of the passengers and is alsoprovided with a pump 20 by means of which any water that may leak in maybe disposed of, the pump being here shown as provided with an operatinghandle or lever 21 and as provided with an intake pipe 22 which leads toa point near the bottom of the boat and an outlet The inlet pipe isprovided with a valve 24. A drain pipe 25 leads downwardly from the tank14 to the pump and has a valve 26. 'Hence, the pump may be used forpumping out water which may leak into the boat and may also be used forpumping out water which may accumulate in the spray receiving tank 14. Avertical tube 27 extends up through the deck 5 and is open at its upperand lower ends. A flag staff 28 for a signal or other flag 29 extendsdown through and is vertically movable in this tube so that it may beraised by a person in the boat in order to display the flag at anelevated position above the boat.

The boat, when arranged on a vessel is supported on skids 80 theoverhang bearing on the skids. A vertical shaft 31 is mounted on abearing 32 in the center of the botpipe 23 which discharges through oneside of the top of the boat.

tom of the boat and has an operating lever 33 at its upper end. A crossarm 34 is secured to the lower end of this shaft and arranged below thebottom of the boat are a pair of locking bolts 35 which are movableradially under the bottom of the boat and have their inner endspivotally connected as at 36 to the said cross arm at points near theends of the latter. These locking bolts are arranged to operate inguides 37 under the bottom of the boat and their outer ends are adaptedto engage keepers 38 with which the skids are provided. The boat isnormally locked to the skids by the bolts. When the boat is to be usedit may be detached from the skids by turning the shaft 31 soas towithdraw the bolts from the keepers as will be understood and this maybe readily done by one man. A light but suffi' ciently strong cable 39is coiled around the top of the boat immediately above the overhang, oneend of the cable is attached to the boat as at l0 and an anchor ll isattached to the other end of the cable. The anchor may be cast in orderto prevent the boat from drifting on rocks and foundering or breakingup.

Signal lanterns or other lights may be hung in the boat opposite theWindows to in dicate the position of the boat at night.

I claim A circular life boat having a bottom of less diameter than theboat, an annular overhang around the bottom, a top rising from theoverhang, and seats arranged radially on the overhang, each seat havinga hinged back adapted to be lowered outwardly and on and to be supportedby the overhang.

In testimony whereof I aflix my signature in presence of two witnesses.
